A flat reasonable fee for a plus service.! it took me many calls to different companies in order to finallyknow ahead of time what i was going to pay to have my dryer vent clean. Unfortunately all of them were giving me "so call estimates" that were not to the point. They were telling me it will cost me between $100-$300. When i pressed for an exact figure (cause i didnt want to hire a service without knowing ahead of time how much i was going to pay) i was told "we cant tell it all depends how long is your vent, etc. And when i gave them the exact lenght of vent, location of dryer, condition, age, etc. They still werent giving me an exact figure. Mr. Tom told me right from the beginning a flat figure without me even giving him any details. And thats exactly how much i paid. He took his time and did his job well. This is how it should be. The cleaning of a dryer vent is not science!
